LOAD

 

Description: This menu lists the options to configure and modify load sets in the DSI database. Descriptions of the various commands in this function are provided in the following sections.

 

Usage:

 

1.  DSI displays the following list of commands in the options area:

 

 

2.  These options are described as subsections in the following pages.

 

-LOAD: STATIC LOAD

 

Description: This function defines and modifies static loads. The loads may be used in the subcase definition.

 

Usage:

 

1.  DSI prompts to select option, as following:

 

   

-LOAD: STATIC LOAD: CREATE

 

Description: This function defines a new load set.  The load set may be used in the subcase definition.

 

Usage:

 

1.  When entering CREATE, DSI prompts to select option, as following:

 

¡¤         The user may enter an integer as the load set number.  If a load set with the entered number exists, the user is prompted to enter a different integer.

 

l           The user is allowed to apply pressure loads to the element centers in the DSI model. Distributed element pressure loads are applied normal to the element surface.  Positive pressure loads are in the same direction as the positive element normal according to the right hand rule.  Negative pressure loads are in the opposite direction of the positive element normal.

 

-LOAD: STATIC LOAD: DELETE

 

Description: This function deletes the selected load set.

 

Usage:

 

1.  DSI prompts:

>   SELECT CARD TO DELETE

   Available load sets are displayed in the STATIC LOAD CARD LIST window.

       

-LOAD: STATIC LOAD: LIST FORCE

 

Description: This function displays the applied forces and lists node numbers and respective loads in the command area of the screen.

 

Usage:

 

1.  DSI prompts:

>   SELECT CARD TO LIST

 

2.  DSI prompts:

>   SELECT NODE FOR FORCE

                       £¿  ALL NODES

 •   All nodes with applied forces will have arrowheads displayed, but no specific load magnitudes will be listed.

NODE

EXIT

 •   Pressing the left mouse button or typing N will list the applied force of the grid nearest to the cursor.

 •   If no FORCES or MOMENTS are applied at the selected grid, DSI will     display the message:

>   NO LOAD SPECIFIED AT SELECTED NODE

and remain in the LIST FORCE option.

 •   EXIT will exit the function LIST FORCE.

 

-LOAD: STATIC LOAD: LIST PRESSURE

 

Description: This function displays the pressure loads and respective element numbers in the command area of the screen.

 

Usage:

 

1.  DSI prompts:

>   SELECT CARD TO LIST

 

2.  DSI prompts:

>   SELECT ELEMENT FOR PRESSURE LOAD

£¿  CURSOR LOCATION

                              EXIT

   If no pressure is applied at the selected element, DSI will display the message:

                         >   NO PRESSURE DEFINED AT SELECTED ELEMENT

                                 and remain in the LIST PRESSURE option.

                             •   EXIT will exit the function LIST PRESSURE.

                             •   If the selected element has a pressure load, DSI prompts:

   >   PRESSURE LOAD AT EL. xxxx = xxxx.xx

 

-LOAD: STATIC LOAD: MODIFY

 

Description: This function modifies the selected load set.

 

Usage:

 

1.  DSI prompts:

>   SELECT CARD TO MODIFY

             •   Available load sets are displayed in the STATIC LOAD CARD LIST window.

   

-LOAD: STATIC LOAD:  REMOVE FORCE

 

Description: This function removes nodal forces from selected grids in the current load set.

 

Usage:

 

1.   DSI prompts:

>   SELECT CARD TO LIST

 

2.   DSI prompts:

>   REMOVE NODAL FORCE

SELECT NODES

 •   The left mouse button may be used to remove selected nodal forces one at a time.

 •   When a nodal force is removed, the node is highlighted by a small circle.

 •   If a node is selected twice, the following message appears:

      >   NODE xxxx ALREADY PICKED

 •   DONE removes the selected nodal forces and exits the function REMOVE FORCE.

 •   ABORT exits the function REMOVE FORCE without deleting the selected nodal forces.

 

-LOAD: STATIC LOAD: REMOVE PRESSURE

 

Description: This function removes pressure loads from selected elements in the current load set.

 

Usage:

 

1.  DSI prompts:

     >   SELECT CARD TO LIST

 

2.  DSI prompts:

>   REMOVE PRESSURE LOAD

>   SELECT ELEMENTS

   When a pressure load is removed, the element is highlighted and the arrow is removed.

   If an element is selected more than once, the following message appears:

>   ELEMENT xxxx ALREADY PICKED

>   SELECT ELEMENTS

    DONE will exit the user to the LOADING OPTIONS submenu.

    ABORT will exit the user to the LOADING OPTIONS submenu without removing any of the selected pressure loads.                                                                                                   

 

-LOAD: STATIC LOAD: SHOW

 

Description: This function shows the selected load set.

 

Usage:

 

1.  DSI prompts:

>   SELECT CARD TO SHOW

             •   Available load sets are displayed in the STATIC LOAD CARD window.

 

-LOAD: DYNAMIC LOAD

 

Description: This function defines and modifies dynamic loads. The loads may be used in the subcase definition.

 

Usage:

 

1.  DSI prompts to select option, as following:

 

 

 2.  When entering CREATE, DSI prompts to select option, as following:

  

 

           •   The functions DELETE, LIST, and MODIFY refer to ¡°STATIC LOAD¡±.

 

-LOAD: NONLINEAR LOAD

 

Description: This function defines and modifies nonlinear loads. The loads may be used in the subcase definition.

 

Usage:

 

1.  DSI prompts to select option, as following:

Description: This function defines and modifies temperature fields. The fields may be used in the subcase definition.

 

Usage:

 

1.  DSI prompts to select option, as following:

 

 

 2.  When entering CREATE, DSI prompts to select option, as following:

 

                     

        •   The functions DELETE, LIST, and MODIFY refer to ¡°STATIC LOAD¡±.
